Abstract
A method for managing log files for recording operations on data stored in a database is provided, wherein a set of log files having an allocated first portion of storage is updated, the allocated first portion of storage is monitored, and a second portion of storage is allocated in dependence on a determination that an available portion of storage is below a predetermined size. A method for generating a snapshot is provided, wherein data entries are included in the snapshot in dependence on a determined relative order of log records in a set of log files. A method of replicating a binary large object is provided, wherein the binary large object is sent to a second database in response to identifying a log record comprising data indicating the binary large object. A method for deleting one or more binary large objects is provided, wherein the data indicating one or more binary large objects that have been logically deleted are stored in a snapshot and the one or more binary large objects are deleted using the data indicating the one or more binary large objects after a previous snapshot is deleted.
